been at this too long, and it's all turning into a maze of twisty passages,
all alike.
:Proposed resolution: **Needs work** (Jeremy)
:Proposed resolution:
Replace:
The reference type of transform_iterator is
``result_of<UnaryFunction(iterator_traits<Iterator>::reference)>::type``. The
``value_type`` is ``remove_cv<remove_reference<reference> >::type``.
with:
If ``Reference`` is ``use_default`` then the ``reference`` member of
``transform_iterator`` is
``result_of<UnaryFunction(iterator_traits<Iterator>::reference)>::type``.
Otherwise, ``reference`` is ``Reference``.
If ``Value`` is ``use_default`` then the ``value_type`` member is
``remove_cv<remove_reference<reference> >::type``. Otherwise,
``value_type`` is ``Value``.
